v1-2: Hedonism and materialism, pleasure and mirth; "I thought in my heart," expressing selfish desires; he soon discovered such things to be worthless.
v3: Mixing wisdom and wine, trying to understand the way of the unbeliever.
v4-6: 'I made my works great, I planted and made.' Here are buildings and gardens, orchards of fruit trees; the writer surrounded himself with attractive things.
v7-8: 'I acquired and gathered for myself.' Here are servants and animals, silver and gold, instruments and singers.
v9-11: The previous verses describe the seeking and gathering of material things, apparently without limit, but without reference to God. Although his heart rejoiced, this was for a short time only, and this was all his reward. The vanity of the human heart is here exposed.
We notice a neglect of others; the psalmist speaks of the wise man who deals graciously and lends (Ps 112.5), of the blessed man who considers the poor (Ps 41.1), but such things are absent here.
v12-13: The truth that wisdom is preferred above folly; it seems that wisdom is light, but folly is darkness, for the fool walks in darkness.
v14-16: The reality of death, and wisdom appears to be useless, for all die, and the wise man is remembered no longer than the fool.
In the face of the certainty of death, there is regret and remorse, but no repentance. Without God, death makes life useless.
v17: The preacher's response, "I hated life." Such was his regret; but unless we see with truly spiritual eyes, we will share that regret.
v18-23: 'I hated all my labour,' bemoans the preacher, thinking that he was spending his life working for nothing.
v24-26: With God life is different, Matt 25.29; Heb 11.6; Job 27.13-17. There is a reward from God, and a life in God. We need to be those who please God. There is value in life, we find, that we should eat and drink, and enjoy the good in our labour; see also 3.12-13; 5.18-20; 8.15; 9.7-9; 11.8-9; the writer opens up a 'stream of hope.' Life is not so bad as he had first thought.
